Thanks, Chris, and thank you, everyone, for joining us today. As you've seen from the press release, we are off to a great start once again this year. For the first quarter, revenue grew 43% compared with last year, our fastest first quarter growth rate in the last 4 years. Our strong growth is a testament to a variety of factors that I want to touch on today and which give us significant optimism for the future. Our performance is especially encouraging because annual advertising budgets are often being reset and reconsidered in Q1, making them historically harder to predict. And this year, the macro environment was challenging with the ongoing global pandemic, war in the Ukraine and the higher rates of inflation around the world. Despite those challenges, we again exceeded our own expectations. I believe we are now firmly established as the default DSP for the open Internet and that we are very well positioned to grow and grab share regardless of the macro environment. We now have over 1,000 customers, representing tens of thousands of advertisers spending on our platform across the open Internet. We continue to see a steady stream of new agencies and brands starting to work with us for the first time as well as existing customers increasing their spend with us. We are seeing strong momentum around key initiatives such as Connected TV, Shopper Data, UID2, OpenPath and our game-changing new data marketplace. In each case, we are working with our advertising clients to drive maximum value from their campaign dollars. And this, in turn, helps us grow our trusted relationships with the world's leading brands and agencies, many of whom are signing long-term strategic partnerships with us. As a CEO, it's always important for me to look at how we are performing relative to the industry. For example, the IAB and PwC predict digital advertising will increase approximately 8% in 2022. Publicis Group's Zenith estimates the increase at about 14%. But either way, we continue to grow at a pace well ahead of industry estimates, which means we are gaining share and adding significant value. I continue to be extremely optimistic in part because of the combination of our exceptional 95% plus retention rate and our significant growth rate. There are macroeconomic forces, which have changed the media and technology landscape dramatically in the last few months, especially in CTV, which also gives me optimism. As many of you know, I have spent many of the last 10 years publicly predicting that Netflix and nearly everyone else would eventually show out. Netflix recently announced that they are likely to make ads a part of their future. This and so many other great things are happening in CTV. In fact, I can't think of a time that the TV landscape has had more positive changes in a short period of time than what has happened in Q1 of this year. I want to spend the biggest lot of time on that. But in order to discuss the significance of what's happening in CTV, we first need to discuss what's happening with 2 foundational initiatives: first, our work on a new identity framework for the Internet; and second, our work to make the supply chain more efficient. So first, identity. The Internet has been operating on a quid pro quo since it became commercial, but the Internet has been a suboptimal Internet. And by that, I mean we've used cookies as a make-shift technology to enable relevant advertising. But due to a series of events and choices, cookies are going away. Currently, Google has the majority of the browser market share around the entire Internet outside of China. So they decided when this transition is going to take place, and they currently targeted the end of Q1 2023. This has created a very unique community to upgrade the Internet. Indeed, without those many circumstances, this opportunity wouldn't exist. We are upgrading from an opt-out Internet to an opt-in Internet. The open Internet is scrambling to coordinate and collectively upgrade. Many different opt-in IDs are being created. Some of them will scale and survive, some won't. However, those that scale will be distributed, encrypted and interoperable. We don't believe IDs can or will scale if they don't upgrade the experience for consumers. With this in mind, we developed and launched UID2. This is the second version of UID, version 2 being e-mail and phone number-based instead of cookie-based. This allows consumers to take their privacy settings and controls with them all over the Internet without loss of control or a false sense of security. Some of the privacy protection that has been promised to consumers by large technology companies with billions of log-ins have misled some consumers to believe that they control privacy, opt-in and the quid pro quo of the Internet across CTVs, mobile environments and computer browsers. UID actually does enable consumers to set preferences and restrictions for each Web publisher, mobile app and CTV app. They choose who they trust and can change their mind. Their preferences are tied to an encrypted, hashed, salted ID based on e-mail address or phone number that a consumer can take with them. Because this move to an upgraded opt-in Internet is scheduled to happen in about 10 months based on the date Google deprecates third-party cookies in Chrome, the entire open Internet ecosystem is thinking about identity, and we continue to make significant progress with UID2. And I'd like to spend a few minutes talking about this progress and the various innovations that are driving that progress. In terms of the number of unique IDs, we are now measuring UIDs on billions of devices. With every passing month, we are posting new all-time highs. That comes as more advertisers activate on UID2 and as more publishers adopt it. Let me give you one quick example, which is particularly illustrative of the business value of UID2. MediaVine is a company that manages advertising for more than 8,500 independent publishers. Those include some large publishers like the Hollywood Gossip and some very niche publishers like Steamy Kitchen. They're big. They are a comScore top 5 lifestyle media platform with more than 130 million monthly viewers and 17 billion monthly ad impressions. MediaVine has now adopted and deployed UID2. Their publishers have seen CPMs increase more than 100%. With UID2, they can create privacy safe identifiers for their readers, pass those on safely to advertisers who can then serve relevant advertising without ever knowing anything directly identifiable about the reader. Better opt-ins and more sign-ins, including new lightweight SSOs, is what a post-cookie Internet is going to look like. And pioneering advertisers, publishers and CTV providers are building that Internet now. Momentum is amazing, but we're still in the early stages, simply because the Internet is so big. This work is both inevitable and essential. Without relevant advertising, CPMs will [crater]. That's the fundamental value exchange of the Internet, relevant advertising in exchange for free content. That's why so many publishers are implementing UID2 with many already reporting strong CPM growth. The ecosystem of UID partners also continues to expand. InfoSum, a leading data collaboration platform, recently signed up as another closed operator of UID2. Many leading advertisers and their agencies, including Omnicom, already use InfoSum to activate their first-party data and are excited about this partnership as they look to unlock the value of that data while maintaining control over it using UID2. AppLovin also recently joined the UID ecosystem. AppLovin is one of the world's leading mobile in-app ad exchanges, and our advertisers now have access to ad opportunities across more than 140,000 apps and 1.8 billion devices with the precision and relevance that UID2 creates. The solutions such as UID2 allow us to manage that value exchange in a way that improves the experience for all parties. I believe this new approach will ultimately result in an upgrade to the Internet. We also recently announced that we are launching a version of UID2 that will be tailored for the European market called EUID. To understand the connection between UID2 and EUID, consider an analogy to Chrome and Chromium. Chromium is a free open-source development platform for Web browsers. Many browsers use core elements of Chromium, including Google Chrome, which uses Chromium as a foundation, but which is enhanced and adapted by Google. Essentially Chrome is one iteration built on top of Chromium. In the same way, UID2 is an open-source project and EUID is a version of it, developed for Europe that meets the specific needs of that market, especially the legislative requirements. Building this specific version also allows us to build in the features that give our partners reassurance that data will not leave Europe, even for international companies that do business and have data in Europe. With this approach, we believe that EUID is the most GDPR-compliant identity solution in the market today. In order for the open Internet to thrive, it will require more authentication or logging in. High CPMs and relevance will gravitate to publishers and content owners who have logged in users. CTV and new sites and apps especially have a unique opportunity at this moment as the identity foundation of the Internet being rebuilt. The CTV leaders understand this. Nearly every CTV ad is shown on the authenticated side of a log-in, almost always via an e-mail or phone number, which means CTV already operates in an opt-in environment unlike much of the rest of the Internet, which is still an opt-out, although it's transitioning. Within that environment, broadcasters can work with advertisers to build the new identity fabric of the Internet that provides addressability while significantly upgrading consumer privacy. And new identity solutions, including UID2, are key here. With UID2, advertisers can safely onboard first-party data. And then with interoperability with CTV apps, they can find valuable audiences, both current and prospects, exactly when they are viewing their favorite premium content. Ultimately, this is a much better advertising experience than one based on cookies. Cookies were never really intended to do this work. They were just co-opted. But in new technology environments like CTV we can build a new identity framework that allows advertisers to create relevance, enables publishers to maximize yield and hand consumers much more control over their privacy. So in many ways, the CTV ecosystem will pioneer the future of identity. To be clear, it's not about any one identity solution. It's about interoperability. This new fabric will include new currencies such as UID2, but also other identifiers, whether it's those developed by CTV providers themselves, measurement, partners like Nielsen or by companies such as LiveRamp. And we are working with all of them to ensure this new fabric pays off those promises I just outlined for all participants. There is so much to discuss today that I'm going to bookmark a related issue that I'd like to discuss in a future call, our data marketplace. The data marketplace is as healthy as ever, largely because UID2 and a better opt-in environment creates a better foundation for our data marketplace, which has the potential to become the largest in the world. I don't think any walled garden can ever create a data marketplace to rival it. Already, we have enacted massive marketplace design upgrades. As a result, we're already seeing higher data usage, better CPAs and ROI for advertisers, better margins and a faster spinning flywheel for us. We have once again stair-step increased the consumer surplus of our offering to our clients. There is so much more to report on this and more change and benefit to come, so I'm excited to talk about that in the future. Related to all the progress we're making with UID is the recent launch of OpenPath. We announced it in our last earnings report, and I'd like to give an update today. First, a reminder of what it is. OpenPath is a way for our advertisers to plug directly into publisher inventory via our platform. By plugging in directly, publishers have the opportunity to capture the value of an opt-in Internet and implement changes that benefit all participants, including advertisers and agencies. I do want to reiterate that this does not mean that The Trade Desk is getting into the SSB or supply side business. OpenPath is simply a direct path to inventory with publishers that already have their own yield management solutions. OpenPath helps eliminate steps in the process where there may be fees or charges with no value in return. For example, since we announced OpenPath, we have shut down Google's open bidding on our platform. When we announced OpenPath a few months ago, we also had commitments from news organizations that represent a majority of news consumers in the United States, organizations such as Reuters, the Washington Post, Gannett, Conde Nast, which owns Vanity Fair, Vogue, The New Yorker and many others, McClatchy, which owns more than 30 leading daily newspapers, including The Kansas City Star and the Fort Worth Star-Telegram, Hearst Magazines and Newspapers, which operate major titles such as the Cosmopolitan and the San Francisco Chronicle, the Tribune Group and several others. In the days following the announcement, we had more than 100 inbound inquiries from major publishers looking to join the initiative. We're prioritizing journalism as we launch OpenPath because nowhere is the danger of the absence of identity more apparent. Recently, we announced more journalistic publishers committing to OpenPath, including the L.A. Times, BuzzFeed, Forbes, MediaVine and Red Ventures, which includes publications such as CNET and Lonely Planet. As more publishers adopt OpenPath, they will make UID2 deployment or interoperability a key element of their plan. In doing so, they can activate their own first-party subscriber data in a way that protects that data but also provides enough relevance to advertisers that we can enhance the value of those ad impressions and yield for publishers. For those that don't show most of their ads after a user has logged in, OpenPath will include a simple UID2-based SSO that will help them make this essential transition to a post-cookie environment. Let me bring this back to CTV because CTV is really the epicenter of open Internet identity. We've seen massive moves in the CTV landscape recently. In 2021, we added exponentially more inventory, thanks to new partnerships with a wide range of partners, including Peacock, Paramount Plus, Discovery Plus and Sky. Early this year, we entered a scaled relationship with HBO Max, one of the most recent and fastest-growing content companies to aggressively adopt ad-funded subscriptions for consumers. On a more macro level, Amazon bought MGM and streams ads through IMDB TV. Just this year so far, Disney+ announced that ads would be added as a choice to their app. Microsoft acquired Xandr. Time Warner left the AT&T family and is now owned by Discovery and is mostly led by Discovery Plus leadership, which is one of the most savvy programmatic teams in TV. And of course, Netflix recently announced that it will likely make ads available on their platform. These major changes in the landscape have huge implications for the future of CTV and programmatic. A tailored TV ad is probably the most effective scaled advertising available today on or off-line. As a result, for most of our clients, TV is the largest segment of their campaign spend. That unique combination of video and audio delivered at a time when the audience is leaned in, remains the most effective way to touch the hearts and minds of consumers. As those consumers have shifted in mass to streaming platforms, advertisers are following them. For consumers, on-demand content is just better. As content owners and the streaming apps are competing for more subscribers, it has become very clear, providing consumers with choice is the only way to win. This is a great setup for Netflix. By not having ads to date, Netflix has protected an amazing user experience, but it required Netflix to keep raising prices so that they could keep making and buying content. At some point, price becomes an issue for nearly all consumers. Consider what we can learn from TV of the past. Even in the days of cable bundles, very few consumers pay for every premium channel, Showtime, HBO, Cinemax, NBA League Pass, et cetera. In the past, nearly all channels have had ads. Now once again, consumers will have something better, choice. Netflix will very likely set up a clean option for consumers, see ads and pay meaningfully less or pay slightly more and avoid ads altogether. Consumers will continue to be given more choices. I predict that with this move, Netflix will continue to be something of a pace car in TV innovation. They were the first ones to really nail the subscription model for CTV. They were the first to 100 million global subscribers, the first to 200 million, and they continue to lead that race today. And now they are embracing consumer choice as a way to expand their market share even further. It's important to note that at least half of Netflix subscribers are outside the United States. So the implications to this move has global ramifications to the world of CTV. But there will even be more to this part of the story. As Netflix explores advertising options, they will be unburdened by legacy processes that some of their competitors are working through. For example, they will be able to structure their advertising operations so they don't have sales channel conflict. They can be data-driven from the start in everything that they do, using data to ensure that they maximize yield on every ad impression. In all of these dimensions, and likely many others, I believe Netflix will continue to innovate and set the pace. And as with any market, others will have to adapt accordingly. Many of them already are. We are working on these opportunities with leading CTV providers every single day. HBO Max, Disney+ and Netflix are all public about their intentions to implement ad experiences. This adds pressure to all content owners to accelerate the move to data-driven buying and selling and finding ways to make the most competitive consumer experience, which means limited relevant ads with high CPMs. For CTV to continue to produce the amazing and expensive content that is driving this new golden age of television, relevant ads are the only way to fund and preserve it. This requires CTV to participate in the open Internet because in walled gardens, one cannot control universal reach and frequency. Additionally, I believe this means every CTV company around the world is racing to create this optimal viewing experience. CTV has historically competed regionally due to the licensing and broadcast regulations. Netflix and YouTube have made this a global race. We're seeing content owners all over the world quickly adapting to these recent moves. Recently, I've personally spoken about this directly with some of our content partners in the United States and in Europe. They are already feeling the pressure to move fast and to improve their ad experiences. This messaging from Netflix, Disney+ and HBO Max is requiring everyone to embrace biddable environments and move away from legacy models like upfronts and even programmatic guarantees where advertiser choice is limited. These changes in the TV landscape also have adjusted marketers' mindsets. As advertisers are seeing reach and impact erode from traditional cable television, they are focused on moving to premium streaming content. Increasingly, this is the most important buy on the media plan. Marketers want to advertise against premium content as much as possible. It's content they can trust. It's content that reflects their own brand. It's content they can activate on and measure against with precision. As advertisers prioritize ads on premium content on our platform, they are beginning to start their campaign planning there, too. As a result, user-generated content is increasingly getting the leftovers. With the explosive growth of premium CTV over the last few years, especially the last year, the trend is clear. We see it clearly reflected in some of the UGC data that's been reported out in the last few weeks, and it's also why CTV remains by far our fastest-growing channel and why premium video in all of its forms has become the largest segment of our business. This trend will be equally apparent internationally where there is also a flight to premium content. We work with many of the Fortune 500 companies, almost all of whom direct their advertising campaigns at multiple international markets. As more premium supply comes online, particularly premium video, we have more than enough demand to satisfy it. And we could not be more excited about what this shift from Netflix, Disney+ and HBO Max means in terms of opening the door of AVOD supply. Not only in major markets that have already embraced CTV advertising such as Western Europe and Australia, but also in many other markets where AVOD will be a vital driver of subscription growth because of tighter economic pressure on consumer wallets. Premium video, where everything is authenticated, is one of those key areas where the future of Internet identity is being forged, not just for CTV, but across the open Internet, including inside the browser. That may not seem obvious as cookies are not present in CTV. And so you'd think they'd be less affected by the potential phaseout of cookies next year. But CTV needs persistent identity to have effective and high CPM ads, and they need high CPM ads to fund that content. It's economics that's driving that process. As more CTV leaders embrace advertising, they want to ensure that they create as much addressability as possible because that's the only way that they can maintain high CPMs. An advertiser will pay, say, a $12 CPM if they know the viewers are watching the latest hot reality show, but they will pay 3x that if there's a reasonable chance those viewers are interested in their product. And that's why they will be among the pioneers of the new identity framework or the open Internet. I'd like to wrap this up by bringing us back to the market opportunity in front of us. The global advertising industry is moving rapidly towards a $1 trillion TAM. As the market grows, the majority of that spend will be digital, and all of it will ultimately be traded programmatically. At the same time, the industry is making important progress in several dimensions in building the Internet advertising ecosystem of the future, one that no longer relies on cookies. The Internet is getting an upgrade. We're moving from an opt-out Internet to an opt-in Internet. Everything is founded on a better identity framework. On that foundation comes better controls for consumers, more choices for consumers on how to pay for CTV subscriptions, whether that's with money or with ad time, and better measurement and data. As the ecosystem continues to evolve and move away from walled gardens led by CTV, we will unleash the power of programmatic for our advertisers and for our publisher partners. It will be an improved experience for everyone, consumers included. The innovations we are driving to help accomplish this are already delivering performance improvements for us today. They are a key factor in why we are off to such a positive start in 2022 and why we are so optimistic about our growth opportunities looking forward. As I said earlier, advertisers are increasingly gravitating to our platform as the de facto DSP of the open Internet led by CTV. And we will continue to innovate to reinforce that leadership position and deliver more value to our advertisers. Our profitable business model allows us complete flexibility to make these investments and continue to drive growth. In doing so, we will help build a better Internet for all stakeholders, and all of that is what makes me so excited about our growth prospects. With that, I will hand the call over to Blake, who will take you through more of the financial details.
